The entry state is INCMP.After the switch get the layer 2 port information of the VLAN, the neighbor entry enters the REACHstate.z Mapping a Layer 2 port in a VLAN to an IPv6 address and a link-layer address. The Layer 2 portspecified by the port-type port-number argument must belong to the VLAN specified by the vlan-idargument, and the corresponding VLAN interface must exist. After you carry out the command, the
